Bash check if script is running with exact options

I know how to check if a script is already running (if pidof -o %PPID -x "scriptname.sh"; then...). But now I have a script that accepts inputs as flags, so it can be used in several different scenarios, many of which will probably run at the same time.

Example:

/opt/scripts/backup/tar.sh -d /directory1 -b /backup/dir -c /config/dir

and

/opt/scripts/backup/tar.sh -d /directory2 -b /backup/dir -c /config/dir

The above runs a backup script that I wrote, and the flags are the parameters for the script: the directory being backed up, the backup location, and the configuration location. The above example are two different backups (directory 1 and directory 2) and therefore should be allowed to run simultaneously.

Is there any way for a script to check if it is being run and check if the running version is using the exact same parameters/flags?

The ps -Af command will provide you all the processes that run on you os with the "command" line used to run them.

One solution :

if ps auxwww | grep '/[o]pt/scripts/backup/tar.*/directory2'; then
    echo "running"
else
    echo "NOT running"
fi
